System and Adapter Configuration:
The IBM PC Server Advanced Systems Management
Adapter must be configured after installation.
Configuration Considerations:
Ÿ
The adapter uses only adapter COM B for external
communication, therefore a modem or null-modem
cable must be connected to adapter COM B.
Ÿ
To share adapter COM B with the system, adapter
COM B must be assigned one of the following I/O
addresses:
3F8 (COM 1)
2F8 (COM 2)
3E8 (COM 3)
2E8 (COM 4)
Ÿ
To dedicate the adapter COM B to the adapter only,
adapter COM B must be disabled with the adapter
configuration program to prevent the system from
accessing it.
Ÿ
The adapter COM A is not used by the adapter. For
the system to use adapter COM A, it must be
configured with the adapter configuration program.
Ÿ
Each port I/O address covers eight contiguous
address bytes as shown in the table on page 70.
Ÿ
Make sure there are no conflicts between the adapter
port I/O addresses and interrupts you configure, and
previously assigned system I/O addresses and
interrupts.
The adapter can be configured to the following I/O address
ranges and interrupts:
I/O Address Ranges (hex) Interrupts
100–107 3
120–127 4
140–147 5
168–16F 9
188–18F 10
200–207 11
220–227 14
240–247 15
268–26F N/A
300–307 N/A
Note: Any listed I/O address range can be assigned with
any listed interrupt as long as there are no conflicts with
previously assigned system I/O addresses and interrupts.
Ÿ
If you have an EISA Configuration Utility program
(called System Configuration Utility on some systems)
go to “EISA Configuration Utility:” on page 71.
Ÿ
If you do not have an EISA Configuration Utility
program, and the system's Configuration/Setup Utility
has the ISA Legacy Resources option go to
“Configuration/Setup Utility ISA Legacy Resources:”
on page 71.
